The ABOVE code is actually right!! But Here I am Just elaborating it..as what i have used..

-(IBAction)zoomin:(id)sender{

self.view.transform = CGAffineTransformMakeScale(.5,.5);
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.9];
//self.view.transform = CGAffineTransformMakeScale(1.5,1.5);
[UIView commitAnimations];

} -(IBAction)zoomout:(id)sender{

self.view.transform = CGAffineTransformMakeScale(1,1);
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.9];
//self.view.transform = CGAffineTransformMakeScale(1.5,1.5);
[UIView commitAnimations];

}

Yes, you can set the view's transform. In particular CGAffineTransformMakeScale will probably be useful to you.
